The problem is that I can't (or don't know how to) separate security-relevant updates from the rest.

And I have to admit, I'm the kind of person who is nearly incapable of ignoring a ringing phone; the permanent presence of that little icon in my systray that tells me there are updates available is not that easy for me to ignore. :-/

It's not a huge problem for me, all things considered, so I didn't have the motivation so far to look further into that. On Leap, you can choose to just install security updates, which is nice.

How do you handle security updates? Can these be done separately?
